Frequently Asked Questions

What are the essential tools for cleaning a Marlin 39A rifle?

Essential tools include a quality cleaning rod (plastic-coated spring steel), cotton flannel patches, a bronze bristle brush, a 3/32 drift pin for the ejector, and a U.S. quarter for the takedown screw. Hoppe's No. 9 solvent and mineral oil are recommended for cleaning and lubrication.

How do you disassemble the Marlin 39A for cleaning?

The Marlin 39A features a takedown design. Loosen the takedown screw with a U.S. quarter, then give the barrel a light tap to separate the receiver halves, providing access to the internal mechanism and bore.

What type of brush should be used for cleaning the Marlin 39A's bore?

A bronze bristle brush is mandatory for cleaning the bore of the Marlin 39A. Steel brushes should be avoided as they can damage the relatively soft steel of .22 caliber barrels.

What is the recommended lubricant for a Marlin 39A?

Simple mineral oil is recommended over complex proprietary oils for lubricating the Marlin 39A. Grease should be used sparingly on specific high-friction points in the action, such as the lifter/carrier pin and finger lever screw.
